IMPROVEMENT IN. GANE MILL.

WALTER BRIGGS, OF GREEN CASTLE, IOWA. I Y Letters Patent No. `59,889, dated .November 20, 1866.

- SPECIFIOATION. T0 ALL WHOM IT MAY CONCERN: i

Be it known that I, WALTER BRIGGS, of Green Castle, in the county of Jasper, and State of Iowa, have invented animproved Cane Mill; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and letters of reference marked thereon, in which- Figure l is a front elevation orl side view of the machine. I

Figure 2, a plan view of rollers and concave in rear of roller b.

Figure 3, a vertical section through the rollers a Figure 4, view of rollers a a, on the ,lower end of said rollers.

Figure 5, a view of one of the keys. l

The nature of my invention consists in constructing rollers, a a, of wood, through'which is passed an iron shaft, fitting in boxes of metal let in the ends of said shafts and having a concave formed in the lower end of the rollers a a and b, into which is fitted a. convex surface placed on bed-piece e and feed-slide H.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. I

In the construction of my invention I use any form usual to mills of like purpose. In g. I a a are the short rollers, and are made of any desirable equal size; 6 the centre roller, and is larger in diameter than rollers a a this roller is made'of wood, the roller end being in length the same as rollers a a it is then turned down to a suitable size, passing through the top pieceszd, with tenon on the end, for the sweep toV be attached, and to which the power is applied; The rollers a a are made of wood, and bored-through the centre. I then insert boxe's c c in each end of the said rollers, and' fit into and through them shaft a', made of turned iron, with journals on each end. In the lower ends of these rollers are concaves K, workingover convex corresponding surfaces on, bed-piece e, the journals resting on va plate of metal attached to bed-pieces. c c, the uprights, to which bed-piece e and top pieces d are attached, forming the frame of the machine. h t arelthe keys for drawing up the machine and tightening the same. o the upright shaft, extending as a part of roller b. the guide for conveying away the stocks-as they pass from the rollers. Z l l Z bolts for binding the top pieces together. I-I the feed slide. l In igs. 2 and 3 like letters designate like parts, as in ig.'1 and iig. 2, m the concave guard in rear of roller b. In iig. 4, K the concave formed in the lower ends of the rollers. B, in g 1, represents the trough or pan to catch the juice as it runs from the press.

' In operating my machine-the stalks are fed through the sliding feed H into the bite formed by the rollers a a and b, and pass through and are guided by concave, `m, around roller b, and brought to the bite of rollers a (on the left) and Z1, when the stalks pass out and are guided out of the way by guard i. The. concave in the lower ends of the rollers, and the convex surfaces under them on bed-piece e, are intended to keep the juice from getting to the ournals and boxes of the different rollers. I find that by the iron shafts being fitted into boxes it prevents the rollers from rising up under great pressure, and is important in my machine. The sliding feed, is moved up and down at the will of the operator, and is kept in its required position by pins p in tig. 1. Having thus described the construction and operation of my invention, what I claim as new, and desire to, secure by Letters Patent, is

1. The rollers a a, with iron shafts and metal boxes, with concave in the ends of the rollers a and b, and convex surfaces operating as described and for the purposes set forth. l

2. I 'claim the sliding feed H, in combination rwith the rollers a a and b, and the concave m, operating as described and for the purposes set forth.
